CASING-SWAGE.

SPECIFICATION forming part of Lettersratent No. 759,379, dated May 1o, 1904.

Application filed September 15, 1903. Serial No. 173,322. (No model.)

thereof is to provide a swage which may be l adjusted for use in many different-sized pipes and in which the swaging portion is readily removable for the substitution of a larger or smaller swage and which may be easily repaired when worn and to provide clearancechannels through the swaging portions for the liquid that is sometimes encountered in a drilled well while the casing is being swaged out.

In the drawings accompanying this application, Figure l a side elevation, partly in central longitudinal section, of a swage embodying my invention. Fig. 2 is a cross-section on the line 2 2A of Fig. 1.

In the drawings, A is the stock, having a screw-threaded shank B, by means of which it is attached to the bit-stock. rIhe lower portion of the stock is reduced in size for the reception oi'- the swaging-collar C, which may be made of highly-tempered steel. Above and below the swaging-collar are the tapered supportingcollars D and E, which are of smaller diameter than the swaging-collar and may be made of less expensive material than the swaging-collar and are tapered to cause the tool to pass more easily through the casing or pipe in thewell. Extending through the swaging-collar and ashort distance above and below it are dowel-pins F, which t in sockets G in the supporting-collars to retain the parts in the same relative position all the time. Extending through the swaging-colporting-collars.

ing collars are retained upon the stock by nut J, which has a squared section J for the reception of a wrenehto screw the parts securely together. This nut may be made of any suitable shape, as its purpose is to hold the parts together.

If desired, the supporting-collars eould be omitted.

Having described my invention, what I claim as new, and desire to secure by Letters' Patent, is-

1. A well-casing swage comprising a stock; a removable swaging-collar having waterways therethrough on said stock, removable tapering supporting-collars of less diameter than the swaging-collar on said stock both above and below said swaging-collar, said supporting collars having waterways therein adapted to register with the waterways in the swaging-collar; means to retain the waterways in the Vswaging and supporting collars in register; means to retain said swaging and supporting collars in place on the stock.

2. A well-casing swage comprising a stock having the lower portion thereof reduced in size; a removable swaging-collar having waterways therethrough on the reduced portion of said stock; dowel-pins extending through said swaging-collar both above and below the same; removable tapering supporting-collars on the reduced portion of said stock, both above and below said swaging-collar, having sockets for the reception of the ends of the dowel-pins which pass through the swagingcollar; waterways through said supportingcollars adapted to register with the waterways in the swaging-collar; and a nut on the end of said stock adapted to retain said swag-l ing and supporting Collars in place thereon.

In witness that I claim the foregoing I have hereunto subscribed myname this 13th day of August, 1903.
